Chiller Breakdown

Leak Repairs

A large proportion of chiller breakdowns are caused by poor brazing. Leaks often occur on the joint between two parts. Work hardened and corroded copper needs to be made just like new to prevent future chiller breakdowns. Instead of just brazing the component up, we completely remove it. Where pipe work is being adapted, old copper pipe is annealed (heat treated) to make it soft and malleable. It is degreased, cleaned up with an abrasive disk, emery cloth, then cleaned a second time with a clean wire brush. Our team of engineers are ACRIB trained and certified with years of industry experience. The system is pressure tested to BSEN 378 to ensure the integrity of the system. All this ensures the chiller does not breakdown again shortly after the repairs

Refrigerant Handling During Chiller Repairs 

During chiller repairs it is essential to consider the environment

Ozone layer and Global Warming


We all remember when the hole in the ozone layer was discovered. It was found to be caused by chlorine in the refrigerant. Chlorine takes a long time to break down in the high atmosphere. Therefore CFCs (chlorofluorocarbons) were phased down then banned


Hydrochlorofluorocarbons were used as a stepping stone until chlorine-free refrigerants were developed. HCFCs too have been phased down and banned


Now many are using HFCs (hydrofluorocarbons) Although they do not contain chlorine- they have high Global Warming Potential, so they too are being phased down


The up and coming man made chemical is HFO. It has been reported to be harmful to marine life


Ammonia has always been a pre-eminent refrigerant. New ammonia chillers are simpler and cheaper- so ammonia is the future!

Engineer Training

Because of the above, the industry has demanded better and better engineers. All our engineers go through 4 years at college to achieve City & Guilds/ NVQ 3 in Complex Systems. Our engineers are put through F-gas refrigerant handling certification and BESA Ammonia training. All this is to educate the engineers and the customer in the correct way to recover and dispose of refrigerant safely

Dalton's Law of Partial Pressures

That all gasses in a vessel will act as if they are on their own. In a poorly maintained condenser, there can be non condensables- air usually from poor chiller repairs. The air sits on top of the liquid causing higher head pressure and false readings of subcooling. The chiller repair involves the refrigerant being recovered into a vessel, then a full system overhaul

Charles's Law of Constant Volume

That in a vessel, pressure is increased or decreased when temperature is increased or decreased. A 10 bar pressure test will go down 0.2 bar overnight if it was 26° when the pressure test was started and in the morning 20° Charles's law of constant volume works with a chiller pressure test because nitrogen is a perfect gas
